AXLE-BOX.

SPECIFICATION forming part of Letters Patent No, 332,809, dated December 22, 1885.

Application filed J une 12, 1885. Serial No. 168,466. (No model.) Patented in Belgium May 20, 1885. No. 68,936, and in England May 20, 1885, No. 6,191.

To all whom it may concern.-

Be it known that I, LORENZ LEIRER, a subject of the Emperor of Austria-Hungary, residing at Buda-Pesth, Austria, Hungary, have invented a new and useful Improvement in Axle-Boxes and Rotating Axles, of which the following is a specification.

This invention relates to axle-boxes and rotating axles for vehicles, whereby an easy and noiseless motion of the vehicles is obtained; and the invention consists of an improved construction of axle-boxes and rotating axles, as will be fully described hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 represent side elevations, respectively, of the upper and lower parts of my improved axle-box for vehicles. Figs. 3 and 4. are respectively a bottom view of the upper part of the axle-box and a top view of the lower part of the axle-box. .Figs. 5, 6, and 7 are details of the parts forming my improved rotating axle for vehicles, and Fig. 8 is a plan of the ax e.

In the drawings, A and B represent, respectively, the upper and lower sections of my improved box for vehicle-axles. The axle-box A B has a journal-bearing, a, at the center of which is arranged an annular groove, 1), as shown in Figs. 3 and 4. The groove 7) serves as a space for the lubricating material, which is introduced through an opening, I), in the upper part, A, and supplied from a box, 0, having a hinged lid closed by a spring, 0. The box, a, for the lubricating material can be made of any suitable shape and construction, and may be located at any suitable part of the axle-box A B. I The front and rear faces of the axle-box are provided with ring-shaped recesses d d, that serve as dust-guards for the journal. These recesses 61 d inclose the axle in such a manner that a nearly-continuous surface is obtained. The lower part, B, of the axle-box fits by lugs e 6 into corresponding sockets, ff of the upper part, A, by which a reliable connection of the parts is obtained. The axle-box is attached to the body of the vehicle in any suitable manner-as, for instance, by straps, screws, or other devices.

The axle rotates in the axle-box A B, and is made of two sections, 7c is, that are connected at the center by a coupling, g, as shown in Fig. 8. The axle-sections k k are provided at the journals h h with annular collars i i, which fit into the annular grooves b b of the axleboxes A B. Each axle-section is provided at both sides of the collars M with shoulders 19 9, that fit into the recesses or dust-guards d d. The axle may be arranged with one or more collars, i i, at each end, and the axle-boxes with a corresponding number of grooves, b b, or the collars and grooves may be entirely dispensed with, as desired. The wheels are rigidly attached to the axle and rotated therewith.

The coupling of the axle-section is shown in detail in Figs. 5, 6, and 7, and has for its object to permit the easy turning of either vehiole-wheel independently of the other when turning curves. For this purpose the axlesection It is provided with an inner tapering end, Z, which fits into a socket, m, of corresponding size at the inner end of the outer axle-section, 7c. The connection of the axlesections is made by means of a ring-shaped screw-nut, n, which screws into the interiorlythreaded end n of the socket on. The enlarged annular head of the screw-nut n prevents it from entering too far into the socket m. The nut n is secured to the socket m by means of one or more screws, 1 r, as shown in Figs. 6 and 7, whereby a reliable connection of the axle-sections k 70' is obtained. The screw-nut a is further provided with arecess, o, by which the same is taken hold of in screwing in or unscrewing the same.

The lubricating of the axle-sections within the coupling 9 is accomplished by an annular oil-duct, a, which is closed by a screw-plug, a. Either the front or hind axle may be made of one or two parts; but when they are made of two parts they are united by a suitable coupling and supported on two or more axle-boxes, as the case may be.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the parts A B, having journal-bearings a, recesses or dust-guards d d, and lubricating-chamber c, substantially as set forth.

2. The combination of the box parts A and B, having journal-bearings a and dust-guards IOu d d, with a rotating axle, his, having journals In testimony whereof I have signed. this h h and shoulders 19 19, substantially as specispecification in the presence of two subscribfied. I ing witnesses.

3. Thecombination of the partsAB, having LORENZ LEIRER. 5 journal-bearings a, an annular groove, 1), and Witnesses:

dust-guards d d, with a rotating axle, k k, SAMUEL WERTHEIM, having journals h h, collars M, and shoulders JAMES RILEY WEAVER.
